Patented Apr. 15, 1924s AUXILIARY SAFE LOCK.

Application filed July 5,

To all whom it may concern:

Be it known that I, ARTHUR E. ANAKIN,

a citizen of the United States, residing at Long Beach, in the county of Los Angeles 6 and State of California, have invented new and useful Improvements in Auxiliary Safe Locks, of which the following is a specification.

My invention relates to vault and safe looks, and more particularly to an auxiliary lock for safes of that character which are normally maintained in a non-locking position but which are adapted to be automatically moved to locking position when the primary lock is burnt or blown out, thereby securely locking the safe door against opening.

It is the purpose of my invention to provide an auxiliary safe lock of the above described character which is of extremely simple, durable and efficient construction and which eliminates the use of springs or other elements which in due time lose their resilient properties, so that they no longer function.

It is also a. purpose of my invention to provide an auxiliary safe lock which operates in such a manner as to prevent the possibility of the lock being unintentionally moved into locking position certain portions of the lock being adjustable to vary the force necessary to move the lock to locking position, so that when once set to accord with the particular conditions, it can be moved to locking position only when the primary lock of the safe is removed.

Although I will describe only one form of auxiliary safe lock embodying my invention and point out the novel features thereof, in claims, it.is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and spirit and scope of the claims.

In the accompanying drawings,

Figure 1 is a view showing a conventional form of safe having applied to the door thereof one form of auxiliary lock embodyingmy invention;

Figure 2 is a fragmentary sectional view of a portion of the safe shown in Figure 1 with the door in closed position and the lock in locking position;

tical section the lock shown in the preceding views;

Figure a is a bottom plan view of the lock shown in Figure 3;

Figure 5 is a fragmentary view partly in section showing a modified form of auxiliary lock embodying my invention.

Referring specifically to the drawings, in

which similar reference characters refer to similar parts, my invention in its present embodiment comprises a metal sleeve 15 closed at its lower end, as indicated at 16 and having a reduced upper end to provide an annular shoulder 17. The upper end of the sleeve is beveled as indicated at 18, to facilitate the outward flaring of this end when the sleeve is in applied position within a door. A collar 19 is secured to the lower end of the sleeve 15 by means of a set screw 20, and this collar is adapted to support a bolt projecting member, designated generally at 21 The belt projecting member, in the present instance, comprises a lever including a relatively long arm 22 and a short arm 23 connected by a vertical portion 2a.

Asclcarly shown in Figure l. the collar 19 is provided with spaced. ears 25 and extended through. these ears is a bolt 26 carrying a nut 27 and a lock washer 28. This bolt 26 provides a pivot for the bolt projecting member 21, and as shown the bolt is extended through a suitable opening formed in the vertical portion 24 of the lever. Vith the lever so arranged, the arm 22 extends through a slot 29 formed in the sleeve 15 so as to engage the lower end of a bolt 30. This bolt 30 is slidably mounted in the sleeve 15 and is adapted to occupy a non-locking position, as shown in Figure 3, or a locking position, as shown in dash lines in Figure 3. The bolt projecting member 21 is designed to move the bolt 30 to the locking position, it being understood that normally the bolt gravitates to non-locking position. By rocking the lever from the position shown in solid lines to that shown in dotted lines in Figure 3, the bolt 30 can be raised to locking position wherein its upper end is projected from the upper end of the sleeve 15. It will be clear that toimove the lever to the dotted position it is necessary to exert adownward force upon the free end of the arm. 23

The pressure necessary to operate the lever to project the bolt depends upon the frictional contact set up between the faces of the lever and the confronting faces of the ears 25. The material of which the collar and ears are formed is slightly resilient so that the ears can be compressed by a tighteningof the nut 27 upon the bolt 26. Consequently the friction set up between the lever and the ears depends upon the relative positions of the ears and the adjustment of the nut It will, therefore, be seen that the pressure necessary to operate the lever can be varied in accordance with the adjustment of the nut 27.

In the applied position of the look, as shown in Figures 1 and 2, the upper end of the sleeve is extended through a suitable opening formed in the upper wall of the safe door, a shoulder 17 abutting the inner side of the wall, and the beveled edge 18 being flared outwardly so as to secure the retaining sleeve within the opening. A recess 31 is formed in the safe body so that when the door is in closed position the upper end of the bolt 30 will be in registration with said recess. A flexible member 32, such as a tape, metal strap, or the like, is secured to the free end of the arm 23 and this member is of suiii cient length so as to reach the primary lock 33 of the safe, its lower end being secured by a screw or other suitable fastening 34 to the lock.

lVith the look so applied, it will be clear that when the primary lock 33 is removed inwardly with respect to the door, the force necessary to remove the lock will act upon the flexible member 32 to operate the projecting member 21, thereby causing the latter to elevate the bolt to locking position within recess 31. Because of the friction set up between the lever and the ears 25, it will be clearly seen that after the lever has been moved into the bolt ejecting position, it will remain in such position to retain the bolt in looking position within the recess so that in spite of the removal of the primary lock 33 the door will be securely retained in closed position.

In practice, the nut 27 is so adjusted that the pull upon the flexible member 32 necessary to operate the lever will be about twenty pounds so that during the normal operation of the primary lock the swinging of the door to closed position will be ineffective to operate the lever to cause a projection of the bolt 30 into locking position. This obviously prevents the accidental operation of the lock as is now possible with similar locks heretofore proposed.

Referring now to Figure 5, I have here shown a modified form of auxiliary lock in which the bolt designated 'at 30 is mounted in a tubular sleeve 15*, the lower end of which is closed by a plug 35. Extended through the lower end of the plug 35, and

sleeve 15 is a pin 36. One end of the pin 36 is upset, while the other end is provided with a bifurcated extension 37, such extension being of a diameter greater than that of the pin 36 so as to provide a shoulder at the junction of the two which cooperates with the upset end for securely retaining the pin within the bolt and sleeve. The extension 37 receives the bolt projecting member in the same manner as the arms 25 in the first form of lock, the bolt 26 being extended through the extension 37 and provided with a nut 27 for restricting the arms of the extension to control the movement of the bolt ejecting member.
